- Registration Number
- NCT04417907
- Lead Sponsor
- Kimford Jay Meador
- Brief Summary
The objective of this study is to determine whether there are any differences in the cognitive abilities and/or behavioral response of normal healthy volunteers across different titration rates of perampanel.
- Detailed Description
This is a randomized, double-blind, parallel group design across different titration rates of perampanel in healthy volunteers. The study consists of 8 visits, 4 of which will occur at the participant's home, over a 7-week period. One hundred and three (103) normal healthy subjects will be treated with perampanel (PER) at one of four different titration rates: (1) 2mg/day PER for one week followed by 4mg/day PER for five weeks, (2) 2mg/day PER for two weeks followed by 4mg/day PER for four weeks, (3) 4mg/day PER for six weeks, or (4) placebo (0mg/day PER) for six weeks. Cognitive and behavioral function testing along with safety testing will be conducted at screening, pretreatment baseline, the end of each week during the titration and maintenance period.

Group Intervention Description PER 2 Week Titration Perampanel 2 week titration Participants will take 2mg perampanel PO QD for two weeks, followed by 4mg perampanel PO QD for four weeks. Placebo Placebo Participants will take 2mg placebo PO QD for six weeks. PER 1 Week Titration Perampanel 1 week titration Participants will take 2mg perampanel PO QD for one week, followed by 4mg perampanel PO QD for five weeks. PER 4 mg Perampanel 4mg Participants will take 4mg perampanel PO QD for six weeks
- Primary Outcome Measures
Name Time Method Overall Neuropsychological Composite Z-score as a Measure of Direct Comparison of the 4 Titration Conditions Across 6 Weeks of Treatment. At the end of each week of treatment for 6 weeks. Z score of cognitive tests (selected performance measures from the computerized cognitive test battery) and questionnaires (AEP, POMS, QOLIE-cognitive questions) at the end of each week of drug treatment for each titration arm, controlling for baseline measures collected prior to treatment. Various measures were combined collectively (averaged) to compute an overall Z-score for each group at each time point. These included: 1) Executive Function Score of computerized test battery; 2) Processing Speed Score of computerized test battery; 3) AEP total score; 4) POMS total and domain scores; 5) Three cognitive components of the QOLIE-31 (attention, memory, language). The Z-score indicates the number of standard deviations away from a reference population. A Z-score of 0 is equal to the mean. Negative numbers indicate poorer performance compared to the mean and positive numbers represent higher performance compared to the mean.
Composite Z-score of Objective Measures as a Measure of Direct Comparison of the 4 Titration Conditions Across 6 Weeks of Treatment. At the end of each week of treatment for 6 weeks. Z score of objective cognitive tests (selected performance measures from the computerized cognitive test battery) at the end of each week of drug treatment for each titration arm, controlling for baseline measures collected prior to treatment. The Z-score indicates the number of standard deviations away from a reference population. A Z-score of 0 is equal to the mean. Negative numbers indicate poorer performance compared to the mean and positive numbers represent higher performance compared to the mean.
Composite Z-score of Subjective Measures as a Measure of Direct Comparison of the 4 Titration Conditions Across 6 Weeks of Treatment. At the end of each week of treatment for 6 weeks. Z score of subjective questionnaires (AEP, POMS, QOLIE-cognitive questions at the end of each week of drug treatment for each titration arm, controlling for baseline measures collected prior to treatment. Various measures were combined collectively (averaged) to compute an overall Z-score for each group at each time point. These included: 1) AEP total score; 2) POMS total and domain scores; 3) Three cognitive components of the QOLIE-31 (attention, memory, language). The Z-score indicates the number of standard deviations away from a reference population. A Z-score of 0 is equal to the mean. Negative numbers indicate poorer performance compared to the mean and positive numbers represent higher performance compared to the mean.
- Secondary Outcome Measures
Name Time Method Treatment Emergent Adverse Events (TEAEs) Across the Six-week Treatment Period Measure of Direct Comparison of the 4 Titration Conditions Across 6 Weeks of Treatment. At the end of each week of treatment for 6 weeks. Number of TEAEs across the the four titration conditions over the six-week treatment period. A score of 0 indicates no TEAEs. Higher numbers indicate greater TEAEs.
Dropouts Across the Six-week Treatment Period Measure of Direct Comparison of the 4 Titration Conditions Across 6 Weeks of Treatment. At the end of each week of treatment for 6 weeks. Number dropouts across the the four titration conditions over the six-week treatment period. A score of 0 indicates no dropouts. Higher numbers indicate greater dropouts.
